FRRouting Software with EIGRP Support

In September 2016 I wrote the article about EIGRP support in Quagga network routing suite. More than one year later, I am going to check the progress of development EIGRP in Linux again. To do so, I have installed a fork of Quagga –  FRRouting (FRR) with EIGRP support on Linux Core. EIGRP routing daemon included […]

Quagga Routing Software with EIGRP Support

In May 2013, Cisco opened its proprietary EIGRP protocol and released an informational RFC 7868 – Cisco’s Enhanced Interior Gateway Routing Protocol (EIGRP). It gives other vendors an opportunity to implement EIGRP protocol into their devices. A group students led by an assistant professor and Cisco CCIE Peter Paluch who is an instructor trainer at the […]

Linux Core 6.3 as Routing and Switching VMware Appliance

Two weeks ago I finished creating a network host based on Linux Core 6.3 installed on WMware x86-64 virtual machine. I loaded Core Linux with several network extensions that allows host to generate, measure, route network traffic and scan networks. I also wrote a short article that contains a list of loaded extension. Then I went further with […]

OPENVSWICH – Campus Model with Layer2 Access built with Open-Source Applications

In the first tutorial we showed how to create Openvswitch extension and submit it to Tinycore repository. There were also presented after-install steps for Openvswitch adapted for specific Core needs. In a previous tutorial we performed several tests in order to test configuration such as vlans, 8021q trunks and VLAN interfaces widely used in typical multilayer switches. In this tutorial […]

Part2 - Testing Equal-Cost Routes in Linux Core 4.0

Assuming you have your Linux Core compiled with enabled option MULTIPATH, we are going to create simple lab to demonstrate existence of multiple equal-cost routes in the kernel routing table. Picture 1 – Testing equal-cost routes They are two Core boxes presented in our testing topology. Boxes are connected with point-to-point Layer 3 links, residing […]

Part1 - Recompiling Linux Core 4.7.7 for Equal-cost Routes

The article describes steps to recompile Core Linux 4.7.7 with the kernel 3.0.21 in order to have redundant multiple equal-cost routes presented in a kernel routing table. The following two points must be accomplished to get it working. 1. Quagga routing suite Quagga must to be compiled with parameter –enable-multipath=ARG to allow to copy multiple […]

EtherChannel,VRRP, DHCP, OSPF Configuration - Cisco, Vyatta, Microcore

The tutorial shows EtherChanel, VRRP, DHCP and OSPF configuration on Cisco, Vyatta and Microcore Linux.  A campus network (look at figure 1) is created with Access and Distribution layer. Instead of Layer 2 switches in Access layer there is Cisco Router 3725  occupied with NM-16SW module in this layer and Cisco  is emulated by Dynamips. […]

Simple Compatibility test between Cisco, Vyatta and LISA

In the previous tutorials I showed how to create Vyatta and LiSA qemu image. Now, it is time play a little bit with these network devices and to make simply compatibility test between Cisco 3725, Vyatta 6.1 Core and LiSA. I created a test topology with two Vyattas, Cisco 3725 router, with NM-16SW, Cisco 7206VXR […]

Vyatta 6.6 Core Installation on QEMU

What is the Vyatta ? The free community Vyatta Core software(VC) is an open source network operating system providing advanced IPv4 and IPv6 routing, stateful firewalling, IPSec and SSL OpenVPN, intrusion prevention, and more. When you add Vyatta to a standard x86 hardware system, you can create an enterprise grade network appliance that easily scales […]
